I don't use at all my bitcoins except the occasions when I think that using those is and investment which can bring me other bitcoins. This kind of occasions, until now, has been the investments in cloud mining. There were three times when I invested in such kind of sites. One will profits, one without profits and without loss and the third with loss. The overall result (fortunately) was to have the same bitcoins "invested". I tell "fortunately" because now I'm convinced that the cloud mining sites are mostly scam and I don't invest anymore there.
